having great fun with macruby and planning on building a lot of apps with it -- thanks to everybody who has contributed to bringing my favorite language to macs :)<div><br></div><div>that said, i see in <a href="http://www.macruby.org/trac/ticket/1208">http://www.macruby.org/trac/ticket/1208</a> and have now suffered through with experience that proper debugger support in xcode is not currently supported, nor does it appear to be imminent. while i am plenty experienced with building big ruby things without a decent debugger -- i&#39;ve built some fairly huge RoR sites using little more than puts and log grepping -- i don&#39;t think MacRuby will get far mainstream without integrated xcode debugging.</div>
<div><br></div><div>lacking a real vote-up feature in <a href="http://bugreporter.apple.com">http://bugreporter.apple.com</a>, here is my bug submission if anybody else on the list wants to also submit this bug to &quot;vote it up&quot; -- this seems to be the only simple way to send a message, so... submit early, submit often.</div>
<div><br></div><div>cheers, n@<br><div><br></div><div><b>Title</b>: xcode does not offer an API to plug in alternate/complementary debuggers</div><div><div><b>ProblemID:</b> 9753880</div><div><b>Product:</b> Developer Tools</div>
<div><b>Version:</b> Xcode 4</div><div><b><br></b></div><div><b>Summary:</b></div><div><br></div><div>Using MacRuby and Xcode4 I can set breakpoints in Ruby files in the UI, but the debugger does not support actually stopping, stepping, etc, nor can it perform language-specific debugging/analysis/expression-evaluation.</div>
<div><br></div><div>Per <a href="http://www.macruby.org/trac/ticket/1208">http://www.macruby.org/trac/ticket/1208</a>, this is minimally a limitation of the debug infrastructure/API in xcode -- there is no API to integrate debugging properly so no effort has been expended to support it in MacRuby.</div>
<div><br></div><div><b>Steps to Reproduce:</b></div><div><br></div><div>1. Create a MacRuby project following the instructions at <a href="http://blog.phusion.nl/2010/03/12/creating-our-very-first-mac-application-with-ruby-how-exciting/">http://blog.phusion.nl/2010/03/12/creating-our-very-first-mac-application-with-ruby-how-exciting/</a>. Use Xcode4 instead of Xcode3 -- Xcode3 will support creating and building the project, but won&#39;t allow you to even set breakpoints in the Ruby files -- it doesn&#39;t understand which lines are code, indentation, etc.</div>
<div><br></div><div>2. Establish a breakpoint at e.g. from the example code some line within MyWindowController.rb::MyWindowController::unveil_full_message_clicked</div><div><br></div><div>3. Build and run the project</div>
<div><br></div><div>4. Click on the &quot;Unveil Full Message&quot; button in the application&#39;s UI</div><div><br></div><div><b>Expected Results:</b></div><div><br></div><div>Debugger stops at MyWindowController::unveil_full_message_clicked and you can inspect variables and evaluate Ruby expressions in the console.</div>
<div><br></div><div><b>Actual Results:</b></div><div><br></div><div>Debugger doesn&#39;t stop. You are now visualizing how you could possibly build an interesting application in MacRuby using only NSLog and puts... hm, challenging!</div>
